Sharepoint List VAlidation setting

Question

I am trying to add validation for my share point lists. I have List with items containing some fields [Delete Item] ,[Scored Status] and some other. I want if the item is scored than user should not be allowed to select the check box for field [Delete Item]. So I am using following formula for same but it doesn't work:

=IF([Delete Item]="Yes",
IF([Scored Status]="Scored", FALSE, TRUE),TRUE)

Answer 1

Add the validation formula to the List Validation, not the Column Validation.

List/Library Settings, List Validation

If the [Delete Item] column is a Yes/No then try this:

=IF( [Delete Item],
 IF( [Scored Status]="Scored", FALSE, TRUE), TRUE)

And you should be able to shorten the above to:

=NOT( AND( [Delete Item], [Scored Status]="Scored" ) )
